GEORGE I. WIGGINTON, OF KALAMAZOO, MICHIGAN, ASSIGNOR TO KALAMAZOO LOOSE LEAF BINDER C0., OF KALAMAZOO, MICHIGAN.

TEMPORARY BINDER.

Specification of Letters Patent.

Patented Oct. 2, 1917.

' To all whom it may concern:

'removal of the sheets,

Be it known that I, GEORGE P. WVIGGINTON,

a citizen of the United States, residing at secure when adjusted, and simple and compact so that it may be readily embodied in a small binder although well adapted for use in larger binders.

Further objects, and objects relating to details and economies of construction and operation will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by thedevices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a partof this specification, in which:

Figure I is a detail inside plan view of a binder embodying the features of my invention with the covers extended, the leaves being shown in an upright position.

Fig. II is a detail inverted view of the adjusting mechanism of the embodiment shown in Fig. I.

Fig. III is an enlarged detail section on a line corresponding to line 33 of Figs. I and II. I

Fig. IV is an inverted detail view corre sponding to that of Fig. II, of a slightly modified embodiment of my invention, a

T single clutch lever being shown instead of the clutchlever shown in Fig. II.

Fig. V is a detail inside view of still another embodimentor modification of my invention. f

Fig. VI is a detail inverted view of the adjusting mechanism of the embodiment shown in Fig. V.

Fig. VII is a plan view of the adjusting lever clutch pawl of the mechanism shown in Fig. VI.

Fig. VIII is a detail longitudinal section on a line corresponding to line 8-8 of Fig. VII.

Fig. IX is an inverted detail view of another modification or embodiment of my invention.

Fig. X is a detail section on a line corre sponding to line 10-10 of Fig. IX.

Fig. XI is an inverted detail view of still another modification or embodiment of my invention.

In the drawing, similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the covers 1 and 2 are preferably provided with clamping bars 3 substantially as shown in my Patent No. 1,022,452, issued April 9, 1912. The binder members 4 are preferably in the form of flexible strips and extend between the covers, being connected to the cover 1 at 5 and to the cover 2 through my improved adjusting mechanism.

The cover 2 is provided with a recess or chamber 6 in which the adjusting mechanism is disposed. This adjusting mechanism comprises a cross-header member 7 slidably mounted on the bar 8 disposed longitudinally of the recessedcover. This adjusting member is retained in its adjusted position on the bar 8 by means of the clutches 9. These clutches are lever-like in form and are mounted on the pivots 10 on the under side of the adjusting member to coact with the bar 8, the clutches having holes 11 therein of such size that when the clutches arc swung forwardly the clutches slide freely on the rod and when swung rearwardly they have a clutching engagement therewith effectively holding the adjusting member against inward movement, that is, movement toward the inner end of the cover, but permitting its outward movement Without disengaging the clutches.

In the embodiment shown in Figs. I, II and III, I provide a pair ofclutches dis- .posed oppositely with their ends projecting at the inner edge 01 the adjusting member so as to be grasped simultaneously with-the grasping of the adjusting member. The clutches are automatically actuated to their 1 engaging positions by means of the springs 11 mounted on the pins 12 with their free arms engaging the clutches at the outer sides of the clutch pivots. I preferably provide stops 13' against which the clutches rest when in their disengaged position.

In the modification shown in Fig. IV a single clutch only is shown. This is quite satisfactory. The double clutch merely provides additional security and divides the stress which would otherwise be carried by the single clutch.

In the modification shown in Fig. the rod or bar 14 is connected to a cross bar 15 to which the binding members 4L- are in turn connected. The bar 14 is supported for longitudinal movement on the cross. piece or support 16 mounted on the cover 2. A clutch 9v is mounted on this support 16 to coact with the bar substantially the same as the clutch in the structures described. The clutch engaging movement, however, is toward the inner end of the cover, while the clutch engaging movement of the structure shown in Figs. I toIV is toward the outer end of the cover, the structure shown in Fig. V being substantially: a reversal of the parts of the structure showninFig. I.

In the modified structure shown in Fig. V, I employ means for applying stress to the binding means. Thiscomprisesa lever 17 pivoted at 18 and provided with a clutch pawl 19 coacting with the bar l l. This clutch pawl, is pivoted on the lever at 20 and provided withia slot 21 through which the bar extends; The outer end of the lever is disposed through the segmental slot 22, the ends of which, constitute stops for the lever. .VVhen the, lever is actuated the pawl.

clutches the. rod 16 moving it toward the outer end of the cover. As the bar slides freely through the clutch 9 in this direction it is unnecessary to manipulate the clutch at, the same time. On the return movement of the leverthe. clutch pawl automatically disengages from the bar. the upper end of the slot2l being rounded. so that it slips freely in the return direction. -A light spring 23 insures thev engagement of the clutch pawl.

, A stop 2,4 is positioned so thatthe clutch pawl engages therewith when the lever is in its initial position thereby insuring the supporting otathe clutch pawl inposition to permit free adjustment of thebar .with% its movement to the .A- pr s 2 is mount n out a communicatin clutch lever;

the support; 16 for returning and holding the clutch: lever inits initial position.

In the mo lifi ation shown IX. and the .lutch 26 is in thehzform menses the clutch is disengaged. The lever is returned by the spring 30. A stop 31 is provided for the lever. The lever shown is a modification of one of the clutches.

In the modification shown in Fig. XI, the bar 8 upon which the adjustin member 8 is mounted is flat in cross section. The clutch member 32 is in the form of an eccentric pivoted at 33 .to coact with the edge of the. bar and provided-witha finger piece or lever 34: disposed through a slot 35in the adjusting llliilllbQl -IO1 convenience manipulation. The clutch is thrown to ward its engaging position byathe spring 36 actuating substantially as the spring 11 in the. embodiment shown in Fig. IV. The clutching movement of the clutch member 32 is awayfrom'the inner end ofthe cover so that stress applied to the adjusting memher through the bindin strips tends to cause a greater gripping or clutching actlon.

With the parts thus arranged I secure a structure which is very simple and secure. in its adjustment. With the several modifi-; cations of my invention illustrated. and described I believe that the application, on adaptation thereof as described will be read: ily understood by those skilled in the art to which my invention relates.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a temporary binder, the'combination with the covers, of binding strips extending between the covers, a bar disposed longitudinally of one of the covers, an adjusting member to which said binding stripsv are connected slidably mounted on said bar, a pair of oppositely disposed lever-like clutches pivotally mounted on said adjusts ing member and through which said bar is disposed, said clutches being positioned with their outer ends projecting at, the edge of the adjusting member so thatthe clutches may be released and the aduisting member grasped simultaneously, springs mounted on said ads pisting member for actuating said clutches having openings therein,

to their engaging positionaand stops for a said; clutches when actuated to disengaged position.

2. In a temporary binder, the combinationot'a bindingmember, a bar, an adjusting member to which said, binding memberis connected adj-ustablv associated with said member to which the covers, of an adjusting means'carried by one of the covers and comprising a bar, and a pivoted friction clutch eoacting with said bar.

4. In a temporary binder, the combination with the covers, and a binding strip extending between the covers, of an adjusting means carried by one of the covers and comprising a bar, and a spring actuated friction clutch coasting with said bar.

5. In a binder, the combination with the covers and a binding strip extending between the covers, of a bar dis osed longitudinally of one of the covers, an adjusting said binding strip is connected slidably mounted on said bar, a lever-like clutch pivotally mounted on said adjusting member and having an opening extending between Copies of this patent may be obtained for therein through which said bar is disposed, said clutch being positioned with its outer end projecting at the inner edge of the adjusting member so that the clutch may be released and the adjusting member grasped simultaneously, a s ring mounted on said adjusting member for actuating said clutch to its engaging position, and a stop for said clutch when actuated to disengaged position.

In witness whereof, I have hereunto set my handand seal in the presence of two witnesses.
